The Sciencent 6 Piece Glass Lens Set has lenses with different curvatures for demonstrating optical principles and effects for students. The set includes one each of the following lenses: double-convex, plano-convex, double-concave, plano-concave, concavo-convex, and convexo-concave. Double-convex, plano-convex, and concavo-convex lenses converge light rays to a point, and convexo-concave lenses diverge light rays from a point. A convergent and a divergent lens paired together will cancel out the optical effect of each lens. Lenses are used in scientific experiments and classroom demonstrations.
